The stock market and investment 总被引:17,自引:0,他引:17
Changes in stock prices have substantial explanatory power forU.S. investment, especially for long-term samples, and evenin the presence of cash flow variables. The stock market dramaticallyout-performs a standard q-variable because the market-equitycomponent of this variable is only a rough proxy for stock marketvalue. Although the stock market did not predict accuratelyafter the crash of October 1987, the errors were not statisticallysignificant. Parallel relationship for Canada raise the puzzlethat Canadian investment appears to react more to the U.S. stockmarket than to the Canadian market. 相似文献

This paper evaluates the impact of Brazil's National Program to Strengthen Family Farming (PRONAF) on the time allocation of household members. We use data from the 2014 Pesquisa Nacional por Amostra de Domicílios, and we apply propensity score methods to complex surveys recently recommended in the literature. We find that PRONAF helps to increase focus on agricultural activities, but it also stimulates female partners to engage in unpaid work. The results show significant effects of PRONAF on child labor and on the gender‐specific division of labor within households, although it does not have the usual adverse effects of rural credit programs on school attendance. 相似文献

A project funded by the Institute for the Study of Business Markets to develop an understanding of the current state of business-to-business marketing and a research agenda for the field identified a lack of understanding of how the marketing function can or should best contribute to firms’ innovation efforts as the top priority. A workshop of senior academics and research-oriented practitioners explored this topic further, identifying four specific themes: (1) improving customer needs understanding and customer involvement in developing new products, (2) innovating beyond the lab, (3) disseminating and implementing research findings in firms, and (4) marketing’s overall role in innovation. This article defines these themes, sketches the current status of knowledge about each theme, frames practitioners’ issues with them, and proposes research agendas for each theme to move the field forward. The goal is to encourage rigorously executed academic research that can also help firms innovate more successfully. 相似文献

Recent research has found that the value‐relevance of accounting variables depends not only on whether a country's accounting rules are code‐law oriented or common‐law oriented, but also on the reporting incentives created by the legal and business environment in which a firm operates. Therefore, for example, the earnings of firms in some countries with common‐law oriented rules but with code‐law incentives have more code‐law‐type characteristics. We further this research by examining whether this is true for firms facing the same accounting regime and institutional environment but different stakeholder‐related incentives. We find significant stakeholder‐related incentives across 23 Japanese firms listed in the United States and 23 Japanese firms not listed in the United States that are matched by industry and size. Although these firms face the same institutional environment and the same accounting regime, consistent with the differences in stakeholder‐related incentives, the earnings and book values of the firms listed in the more shareholder‐oriented U.S. markets have significantly more explanatory power for market value than those for firms not cross‐listed in the United States. These findings are unaffected by whether the reports are based on consolidated or parent‐only accounting or whether they are based on U.S. or Japanese GAAP, emphasizing the potential influence of reporting incentives at all levels on the effect of standardization, conversion, or harmonization of accounting methods globally. 相似文献

After working with hundreds of leaders in a wide variety of organizations and in countries all over the globe, the authors found one very clear pattern: When it comes to meeting their leadership potential, many people unintentionally get in their own way. Five barriers in particular tend to keep promising managers from becoming exceptional leaders: People overemphasize personal goals, protect their public image, turn their competitors into two-dimensional enemies, go it alone instead of soliciting support and advice, and wait for permission to lead. Troy, a customer service manager, endangered his job and his company's reputation by focusing on protecting his position, not helping his team; when a trusted friend advised him to change his behavior, the results were striking. Anita's insistence on sticking to the tough personal she'd created for herself caused her to ignore the more intuitive part of the leadership equation, with disastrous results--until she let go of the need to appear invulnerable and reached out to another manager. Jon, a personal trainer who had virtually no experience with either youth development programs or urban life, opened a highly successful gym for inner-city kids at risk; he refused to be daunted by his lack of expertise and decided to simply "go for it." As these and other examples from the authors' research demonstrate, being a leader means making an active decision to lead. Only then will the workforce--and society--benefit from the enormous amount of talent currently sitting on the bench. 相似文献

We investigate a common‐value labor setting in which firms interview a worker prior to hiring. When firms have private information about the worker's value and interview decisions are kept private, many firms may enter the market, interview, and hire with positive probability. When firms' interview decisions are revealed, severe adverse selection arises. As a result, all firms except for the highest‐ranked firm are excluded from the hiring process. 相似文献

- Nowadays, not‐for‐profit organizations and charities face the ageing of donors and a growing debate over monetary donation collection methods. They need to find solutions to attract younger generations of donors. Could this be done using the same methods applied to older generations? This present research investigates social representations (SRs) of giving by younger generations to understand how not‐for‐profit organizations and charities should approach them. The study focuses on SRs of a French sample of 276 individuals from Generation Y born between 1979 and 1991. It uses the free association technique. The results show paradoxical representations of giving. Institutionalization of giving is salient as representation of it as a freely consenting act. The paradox relies also in the strong presence of a relationship with others that parallels the gift as an individualistic choice.
- Generation Y individuals appear to be sociable, yet they evoke more sharing and solidarity than charity. Institutionalized forms of giving, particularly via charities and not‐for‐profit organizations, are rejected. These individuals seem to express their individuality through practices that resemble sharing rather than giving. From a managerial point of view, these results shed light on the factors liable to cause members of this generation to give, such as (i) the use of social networks, (ii) appealing to pleasure, festivities and efficiency rather than to guilt and duty, and (iii) encouragement to “work within the not‐for‐profit organization”.

Communication and information technologies are adding new capabilities for rapid and inexpensive customer input to all stages of the product development (PD) process. In this article we review six web‐based methods of customer input as examples of the improved Internet capabilities of communication, conceptualization, and computation. For each method we give examples of user‐interfaces, initial applications, and validity tests. We critique the applicability of the methods for use in the various stages of PD and discuss how they complement existing methods. For example, during the fuzzy front end of PD the information pump enables customers to interact with each other in a web‐based game that provides incentives for truth‐telling and thinking hard, thus providing new ways for customers to verbalize the product features that are important to them. Fast polyhedral adaptive conjoint estimation enables PD teams to screen larger numbers of product features inexpensively to identify and measure the importance of the most promising features for further development. Meanwhile, interactive web‐based conjoint analysis interfaces are moving this proven set of methods to the web while exploiting new capabilities to present products, features, product use, and marketing elements in streaming multimedia representations. User design exploits the interactivity of the web to enable users to design their own virtual products thus enabling the PD team to understand complex feature interactions and enabling customers to learn their own preferences for new products. These methods can be valuable for identifying opportunities, improving the design and engineering of products, and testing ideas and concepts much earlier in the process when less time and money is at risk. As products move toward pretesting and testing, virtual concept testing on the web enables PD teams to test concepts without actually building the product. Further, by combining virtual concepts and the ability of customers to interact with one another in a stock‐market‐like game, securities trading of concepts provides a novel way to identify winning concepts. Prototypes of all six methods are available and have been tested with real products and real customers. These tests demonstrate reliability for web‐based conjoint analysis, polyhedral methods, virtual concept testing, and stock‐market‐like trading; external validity for web‐based conjoint analysis and polyhedral methods; and consistency for web‐based conjoint analysis versus user design. We report on these tests, commercial applications, and other evaluations. © 2002 Elsevier Science Inc. All rights reserved. 相似文献

One critical step in new product development is selecting from among multiple possible product concepts the one that the firm will carry forward into the marketplace. There is a need for low‐cost, parallel testing of the appeal of new product concepts, the results of which closely mirror ultimate market performance. In this article, the authors first describe an Internet‐based product concept testing method they developed that incorporates virtual prototypes of new product concepts, substituting them for physical prototypes. The method can be used with either static representations of the products or with dynamic representations that demonstrate how the product works through a simulated video clip of its operation. The objective of this method is to allow design teams to select the best of several new concepts within a product category with which to proceed, without having to develop physical prototypes. The authors then provide a rigorous test of both virtual prototype methods against tests using both physical prototypes and attribute‐only (i.e., no visuals), full‐profile conjoint analysis. Nine concepts compete against two actual products in the tests. Market shares from the test using the physical prototypes are defined as the “actual” market shares. Predicted market shares for the attribute‐only, full‐profile conjoint analysis and each of the two virtual prototype methods are compared to those obtained for the physical prototypes. Both static and animated virtual prototype tests produced market shares that closely mirrored those obtained with the physical products, outperforming the set of predictions across the full range of products produced in the attribute‐only conjoint analysis. Interestingly, the attribute‐only conjoint analysis identified the top three products, in correct order. It was unable to differentiate performance below these top three products. Furthermore, it predicted market shares for the top three products to be well below those achieved using physical prototypes. As virtual prototypes cost considerably less to build and test than their physical counterparts, design teams using Internet‐based product concept research may be able to afford to explore a much larger number of concepts. Virtual prototypes and the testing methods associated with them may help reduce the uncertainty and cost of new product introductions by allowing more ideas to be concept tested in parallel with target consumers. 相似文献
